Suggest checking your compressor first. If it's good, you don't need anything but new orings and receiver/drier (<$30). Ackits.com is a good source for orings, lube, and receiver/drier.

good luck

Drain some oil and examine for any metal shavings. Obviously a no-go.

Look at clutch shaft for evidence of leaking by main shaft seal. Lots of oil/dirt would indicate a problem. Shaft

Your best bet is to simply rebuild the system. At this age, that is usually what is necessary to get good AC performance for the long term. This AC system is easy to rebuild. Here are the basics:

1) Remove the receiver/drier and compressor. Inspect compressor oil for damaged pistons/cylinders. Look for aluminum shavings in oil in compressor and receiver/drier. If OK, adjust clutch gap to spec, Make sure the idler bearing is good and replace if necessary. Replace compressor if any indications of aluminum shavings.

2) If aluminum shavings are detected, it's best to buy a used evaporator and condensor. It is impossible to totally flush these parts and aluminum shavings will damage new compressor.

3) If compressor is OK, remove evaporator and replace all orings on expansion valve and feedback bulb.

4) Replace all ac system connection Orings.

5) Flush all hoses w/ laquer thinner.

6) Reassemble system leaving new receiver/drier to last. Install 5 oz DE PAG oil in condensor, compressor, and new receiver/drier.

7) Vacuum for 1/2 hour and check that vacuum holds for at least 15 mins w/ almost no drop.

8) If good vacuum another 1/2 hr and charge w/ spec amount of R134a.

Enjoy your nice cool air for a long time to come. I rebult my 94EX; new compressor shaft seal, replaced evaporator due to suspected leak. It's still cooling good and running fine today, but I did add a few ounce of R134a last year.

good luck

If you did, then other components should be replaced.
